Stochastic excitation acted on automobiles due to multivariate road roughness is described in detail firstly.Proper orthogonal decomposition(POD) of random multivariate processes is defined.Then,to simulate the stochastic excitation,a set of simplified formulas based on the spectral representation method and POD is given,which can reduce computation with FFT to speed up computing.Since the time-consuming Cholesky decomposition is removed,the simplified method is more efficient than the original spectral representation method.By defining the "road roughness mode" vividly,the physical meaning of POD and this method are clarified.Simulation of the displacement excitation acted on a four-wheeled car is taken as an example.The validity of this method is verified.
